Pokémon GO Plus, JUST AROUND THE CORNERIt’s almost here! Nintendo and The Pokémon Company just announced that Pokémon GO Plus will be available in much of the world next week, on Sept. 16.

Pokémon GO Plus is a companion device that connects to your phone over Bluetooth® Smart (the Bluetooth low energy connection designed for health and fitness applications), allowing you to keep your phone in your pocket and go about your day-to-day activities while still being able to collect valuable resources and capture even the most elusive Pokémon. We’ve been testing it here at Niantic and we love the way it allows you to blend Pokémon GO even more seamlessly into family and fitness activities. Now you’ll be able to play and enjoy your walk, run, hike, park trips or visits to the library without having to look at your screen all the time.

As you pass by a PokéStop, Pokémon GO Plus will vibrate and light up and alert you to the location. You’ll even be able to collect new items just by clicking the Pokémon GO Plus. If there’s nearby Pokémon hiding in your area you’ll be alerted with lights and vibrations; catch the Pokémon with a button on Pokémon GO Plus and then continue on your way (later, you can check your Journal to see which Pokémon you’ve just caught).

Pokémon GO Plus will be available on September 16, 2016 in most countries and later in the year in a few South American territories.

This device is starting to make more sense to me now... Not for being useful, but because maybe using it I could actually walk and find new Pokémon/hatch my eggs, because seriously, the last three days Pokémon GO was unplayable for me.

Sadly, they haven't talked about hatching eggs... and I think that you can catch only Pokémon that you alread have in your Pokédex
Since here you can't find a lot of Pokémon, it's a little wortless for me

So, it means that this device is a piece of junk even more useless than I thought.
